1 Claim. (Cl. 131-12) This invention relates to smokers pipes and pered bore 29 is adapted to be received in the bore more particularly to an improved pipe stem con- I4 of the cylindrical portion I6 of the stem II, struction. It is well known that the ordinary Y and an inner tubular member 30 having ends 3l smokers pipe accumulates a considerable amount and 32 is provided for positioning within the 5 of moisture and tobacco liquor in ordinary use, tapered bore I 4 of the stem, end Y3l being tted Which accumulation is drawn through the pipe into the tapered bore of bushing 28, and the end stern into the mouth of the smoker with its at- 32 of the tube being iitted into the bore I4 at the tendant disagreeable effects and requiring a large tip end of the stem II and terminating slightly amount of cleaning. This objectionable condishort of the tip I5. The tube 30 is preferably of l0 tion is overcome by my present invention by the a thin metallic material and of relatively high l0 novel construction of the pipe stem as will be apthermal conductivity and suinciently soft so that parent from the following description. the ends 3| and 32 may make a tapered fit with It is therefore an object of my invention to the bushing 28 and the taper of the bore I4 at provide an improved pipe wherein the formation the tipend of the stem.

The stem by the lighting of the pipe, from the Warm air II is provided with a tapered bore I4 extending and the smoke passing through the tube, and from the tip end l5 t0 end l5 Which iS Subthe space 33 will permit the tube 30 to remain hot 40 stantially cylindrical. The stem I I is further produring the smoking period, The moisture which vided with a circular bead II and a circular rein other types of pipes forms in the smoke pascess I8.
